SPECIFICATION forming part of Letters Patent No. 335,979, dated February9, 1886. Application filed August 25, 1895. Serial No. 175,316. (Nomodel.)

To all whom it may concern.-

Be it known that I, PLATT B. VIELE, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented new and useful Improvements in Locomotive Head-Lights, ofwhich the following is a specification.

This invention relates to an improved reflector for locomotivehead-lights; and it consists of a concaved or parabolic reflectorprovided on each side with a series of vertical slits or narrow slottedopenings for the passage of light to the numbers or signals displayed onthe sides of the head-light case.

The invention also consists in the combina tion, with a main reflectorhaving verticallyslotted sides, of supplemental reflectors placed oneach side of said reflector, between it and the sides of the head-lightcase, for the par pose of throwing any surplus light toward the numbersor signals on the sides of the casing.

In the annexed drawings, illustrating the invention, Figure l is ahorizontal section of a locomotive head-light made according to myinvention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3is a modification.

Referring to these drawings, the numeral 1 designates a rectangularhead-light casing hav ing face-glasses 2, and provided on each side withthe locomotive or train number, or any desired signal, or with bothnumbers and signals,arranged in any convenient or well'known manner.WVithin this casing is placed a parabolic reflector, 3, or othersuitable concaved reflector of approved style, for throwing lightforward upon the track from a lamp, 4, arranged within the rear end ofthe reflector, as usual.

In order to illuminate the numbers or signals in the sides of thehead-light case a series of vertical slots or elongated slots, 5, areformed in each side of the reflector 3, for the passage of rays of lighttoward and against said numbers or signals. These vertical openings maybe made of gradually-increasing length from rear to front, therebyconforming to the contour of the reflector, and can be made either byremoving narrow strips from the sides of the reflector, as shown in Fig.3, or by simply cutting vertical slits with short horizontal slits ateach end, whereby the partly-cut portion of the reflector can be turnedinward to form vertical wings 6, as shown in Figs. 1 and 2. The openings5 thus formed in the sides of the reflector afford passages for asufficient quantity of light to illuminate the numbers and signals inthe sides of the headlight case without materially diminishing thevolume of light thrown forward upon the track, especially as the slitsor slots 5 do not need to have any great width. The wings 6, when viewedfrom the front of the head-light, serve to partly cover the openings 5,on the front edges of which they are located, and thus form part of thegeneral reflecting-surface.

If desired, a supplemental reflector, 7, of any suitable form, may beplaced on each side of the main reflector 3, between its front end andthe sides of the casing 1, the faces of said supplemental reflectorsbeing either straight, concave, or convex, and turned back ward, asshown in Figs. 1 and 3, so as to receive any surplus light and throw ittoward the numbers or signals. If desired, these supplemental reflectors7 may be set farther back at any suitable point on the sides of the'main reflector, but in advance of the signal or number glasses.

WVhat I claim as my invention is-- 1. In a locomotive head-light, thecombination, with a casing having side numbers or signals, of areflector provided on each side with a series of vertical openings forthe passage of light to said numbers or signals, substantially asdescribed.

2. In a locomotive headlight, the combination, with a casing havingnumbers or signals displayed on its sides, of a main reflector providedon each side with a series of vertical slots for the passage of light tosaid numbers or signals, and supplemental reflectors placed between saidreflector and the sides of the casing, and adapted to throw light towardsaid numbers or signals, substantially as described.

3. In a locomotive head-light, the combina- 5 tion, with the casing 1,having side numbers or signals, of the reflector 3, provided on eachside with narrow slotted openings wings 6, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

PLAIT B. VIELE.
